Summary

Anterior cruciate ligament injuried is the most common joint disorder in the world. But how many strand of hamstring tendon autograft for anterior cruciate ligament reconstruction is unknow.

Abstract

Purpose

The purpose of this study was to evalute the correlation between the Hamsting autograft size and the clinic results.

Methods

One hundred and sixty-three patients of the primary ACL reconstruction with five-strand autograft hamstring tendon were evaluated. All of the patients were divided into two groups according the graft size.The Lysholm system was used to evaluate the clinic results,and the postoperative stability was measured using the anterior shifting of tibia.The revision rates of 2 years postoperation were also canculated.

Results

The graft size of 112 cases are greater than 8mm, and 51 cases are equal or less than 8mm. The revision rate of 2 years postoperation in two groups are 1.79% and 13.73% respectively.The Lysholm scores in the group which the graft size greater than 8mm is better than another group(p<0.05).

Conclusion

We believe that the size of five-strands hamstring autograft more preferable to ACL reconstruction and have less reoperation rate when the graft size greater than 8mm.The technology has good clinical application prospects.
